amp noise?

Hey guitaristdan,

Have you tried this page http://bolt60.no.sapo.pt/? Website dedicated to the Roland Bolt 60. You can probably find a suitable fix to the hum problem there. IIRC it's the FX loop switch and the filter caps contribute to the hum on that amp. I see you had the filter caps changed out. Try looking into the FX Loop switch mod.

thanks drumslinger! "The amp has some constant hum even if the guitar isn’t connected, it can be annoying if you aren’t playing but this hum is normal in all tube amplifiers." thats a quote from the website - good to know!

I'll take a look into that FX loop switch modification, when i find some time. But the amps known for that hum without any guitars plugged into it, so yehh, thanks for everyones input and suggestions. Thats all the info i need


cheers guys, dan
